Performing Measurement

Pulsed Id-Vd Measurement

Pulsed Id-Vd Measurement

Pulsed Id-Vd measurement can be performed as follows.

Figure 4-8

PLSDIV IdVd Test Definition

1. Open the PLSDIV IdVd test definition on the EasyEXPERT application test 

environment.

2. Set the measurement condition to the Device Parameters, Test Parameters, and 

Extended Test Parameters. For the description of the entry fields, see “PLSDIV 
IdVd” on page 5-17.

3. Connect the device under test (MOSFET) as shown in “RF Probes” on page 2-4.

4. Click the Single button at the upper right corner of the EasyEXPERT screen. 

Pulsed Id-Vd measurement is started.

Figure 4-9 shows the pulsed Id-Vd measurement result example.
